When Cleveland is diagnosed with high cholesterol, Donna puts him on a new high-fiber diet, which causes an intestinal backlash. Cleveland sees his doctor, who he hopes will be able to treat his uncontrollable flatulence. He is disappointed when the doctor tells him his farts are normal and are caused by the amount of fiber in his diet. In order to reduce Cleveland's embarrassment, the doctor gives him a "fart card" to help him bypass the social stigma. The card makes other characters more accepting of Cleveland's bad habit, even a police officer who backs off on arresting Cleveland after Cleveland flashes his fart card. Things take a turn for the better when Cleveland realizes his gas might score him a few points in the Broken Stool's karaoke contest. Everyone but Donna is impressed.
